Be it known that I, A uoHInALD F. Horkrysa citizen of the United States,and a residcntof Dixon, county of Lee, and State of Illinois,

5 have invented certain new and useful Improvements in rapping-Machines,of which the following is a specification.

My present invention relates to that class of now well understoodwrapping-machines a by which articles of parallelepiped shape as, forinstance, caramels--are automatically en veloped by wrappers, as ofpaper, properly folded to place: and the object of my invention is toprovide improved means for accomplishing the socalled first" and secondfolds of such wrappers, whereby clogging, stoppage, breakage, anddisarrangement generally are obviated and increased economy, speed. andaggregate output secured. I at tain these objects by the meanshereinafter described. These means are particularly, though notexclusively, applicable to that type of said wrapping machines in whicheach article to be wrapped is, together with a suitable portion ofwrapping material, inserted in a suitably-disposed pocket having itsopening on the periphery of a so-called carrymg-wheel, by theintermittent rotation of which said article and its accompanying wrapperare carried to different points where by the aid of suitableinstrumentalities one or more of the required folds in the wrapper aresuccessively made as the wrapping operation progresses.

In this specilication description is omitted (as unnecessary to acomplete understanding of my present invention) of many of those partsof a completely-organized wrappingmachine, above referred to, notdirectly involved in the operation of my present improvements as, forinstance, of feeding and cutting devices and also folding devices notinvolved in producing the so-called first and second side folds of thewrapper, and it will be understood that any preferred form of suchdevices may be used as are deemed best adapted to cooperate with mypresent improvements or any of them, as now dei being spaced equaldistances apart.

I scribed, reference being bad to the accompanying drawings, in which-Figure 1 is an elevation, on an enlarged scale, of a portion of thecarrier-wheel and its immediate adjuncts sufiicient to disclose itsoperation generally and particularly the operation of my aforesaidpresent improvements. Fig. 2 isafrontelevation of so much of saidwrzmping-machine as is required to show the same of my said presentimprovements and their operation. Fig. 3 is an end or side elevation ofFig. 2 viewed from the lefthand side of the latter. Fig. 4 is a centralvertical section of certain parts of the machine, taken through thecenter of the main shaft. Figs. 5, 6, T, 8, 9, 10, II are details, onenlarged scale, showing successive stages in the folding operation.Figs. 19. and 13 are detail views of parts.

O is the main shaft of the machine constantly rotated by power appliedin any convenient manner to pulley C, said shaft being journaled inproper standards B B lixed to any suitable foundation or bed-plate Y.

I a relatively long sleeve journaled in a sleeve-bearing I", carried byone of said standi ards If. (See Fig. -I.) I is rotative on the mainshaft C. To one end of I is secured said carrying-wheel E, on theperiphery of which are a series of pockets or receptacles 1;, spacedequal distances apart, opening outwardly at said periphery and eachprovided with a yielding strip adapted to hold thearticles to be wrappedwhen inserted in the pocket. Rigidly secured to the opposite end of I isa gear ratchet-wheel I. In axial alinement with shaft O and ri idlysecured to I and thus to base-plate Y, is a Iixed or non-rotativecamdisk E.

Carrying-wheel E is in the present instance provided with eight of saidpockets and is rotated the distance between the centers of two adjacentpockets while shaft O makes a complete revolution. The intermittentmovement of E is accomplished as follows: Eatchetwheel I is providedwith the same number of notches there are pockets in E, said notches Toa standard J (see Fig. 3) is pivoted an arm J, to which is pivoted anarm J engaged eccentrically to a face-plate J rigidly secured toextremity of shaft C. Between said faceplate J 3 and the ratchet-wheel Iis journaled on shaft C a collar K, provided with an arm.

K, extending radially beyond the rim of ratchet-wheel 1 and providedwith a pawl l0, disposed to engage said notches in I. A pulling-springfurther connects pawl and arm K, whereby said pawl is caused constantlyto contact with the periphery of I. A connecting-rod 1', preferablyadjustable, connects arm J with arm K. It follows that inasmuch as arm Jis pivoted on face-plate J eccentrically one revolution of shaft 0causes an oscillation of arm J, which on its upward movement throughconnecting-rod imparts to arm K and so to pawl is, engaged in one of thenotches of, and so to ratchet-wheel I, movements resulting in therotation of the carrier-wheel E one-eighth of a revolution, being thedistance between centers of adja cent pockets, the extent of themovement being adjusted accordingly, as by adapting the length of theconnecting-rod as required, for which purpose any suitable constructionmay be employed. It will also be observed that by reason of theforegoing the carrierwheel E is stationary during part of the rotationof shaft C, and the parts referred to are so adjusted relatively to eachother that while so stationary two of said pockets oppositely disposedin the said periphery thereof pause upon substantially the samehorizontal line, as shown in Fig. 1. By any suitable feeding andcontrolling device the article to be wrapped is while suitablysupported, as upon a feed-chute F, (partly shown in section in Fig. 1,)caused to register with the opening of that pocket at the timestationary and adjacent thereto, and a portion of unfolded wrappingmaterial (as paper, for instance) of req uisite size is by anyappropriate means fed and supported flatly outspread and centeredbetween said article and said opening, whereupon a plungerP is by anyconvenient means caused to advance against one side of the article andpush it, together with said wrapper, through said opening and home intothe pocket. The said wrapper is caused by the movements described towrap three sides of the article against which it is forced and heldowing to said action of said plunger by the resistance afforded by thebottom and front and rear walls of the pocket, the remaining unfoldedparts of said wrapper projecting some of them transversely and othersradially from the periphery of said carrier-wheel, as shown in Figs. 5and 8.

My present invention, as aforesaid, concerns the means provided forimparting and retaining, as will now be shown, the desired so-calledfirst and second side folds to the said radially-projecting portions ofthe wrapper.

The article with its wrapper having been charged into the pocket asaforesaid, the continued rotation of shaft C presently imparts tocarrier-wheel E one of the intermittent one-eighth revolutionsabovedescribed, whereby the pocket, with its charge, is brought withinreach of the folder A, which as the wheel again pauses is actuated tomove in the direction of said rotation against that one of theradially-disposed projections of the wrapper adjacent to said folder andto bend such projection forward over and down upon the article, thusmaking in the wrapper the so-called first side fold thereof. (See Fig.6.) The said operation of folder A is effected as follows: Journaled inbearings a a, Fig. 2, in an arm a, rigidly secured to the fixed cam-diskE, is a rock-shaft (0 having rigidly connected therewith at oneextremity thereof an arm (f. To the arm K and extending at right anglesthereto is rigidly secured an arm (0*. (See Fig. 2.) Said arms a and (oare con' nected by a rod (4 pivotally secured to the free end of each,respectively, the said connection between a and a being effected byheaded pin a, secured to a and loosely held in slot (0 in head a on saidrod a, by which connection provision is made for retarding the inceptionof the retrograde movement of said folder A. On rock-shaft a is looselymounted arm a. A spring (0 is coiled around a sleeved portion of saidarm surrounding said rock-shaft a said spring beingsecured at one end tocollar a adjustably secured to rock-shaft a and having its opposite andfree end in engagement with arm (0, whereby said arm is yieldingly heldto normal position relatively to said rock-shaft (f, the movement ofsaid arm relatively to said rock-shaft being limited by key a on saidrock-shaft engag ing in key-seat a in sleeve of arm a, as shown in Fig.12.

To one end of arm a is fixedly secured pin a. (See Fig. 13.) The folderA is loosely secured to pin or shaft a by ears (L15 a on said folder,journaled upon said pin. A helical spring a bears at one end against aand at the opposite end against A, the action of said spring a tendingto increase the angle between (0 and A, and said action being limited byadjustable stop a on A abutting against suitable projection (0 securedtoa, by which means A is caused to contact yieldingly with the wrapperwhen in position shown in Fig. 6.

From the foregoing it follows that as shaft 0 is rotated at eachdownward oscillation of arm K the folder A is caused to move from normalposition downwardly and inwardly in the direction of the rotation ofcarrier-wheel E against the radially-projecting portion 0; of wrapper V(shown in Fig. 5) and to yieldingly force the same forward anddownwardly in the direction of the article V until said projectingportion is completely folded down upon the latter in the position shownin Fig. 6 to make the first side fold of said wrapper, the articleremaining stationary during the said operation, owing to thehereinbeforenoted intermission in the rotation of the earrier-wheel E.The extent of the aforesaid movement of the folder A is limited by arma" engaging against stop a, secured to a stationary part D of themachine hereinafter described. It will be observed that by rea son ofthe construction described the movement of folder A and arm a relativelyto the wrapper is caused by the action of the spring 11 when rotation ofrock-shaft ff causes key a to move in key-seat It, thus releasing a tobe actuated by spring a. The power of spring is regulated so that onfolder A oncountering in its movement any resistance greater than thatof the pliable wrapper-as, for instance, a misplaced and abnormallyprojecting portion of the article to be wrappedthe movementof folder Aand arm a is thereby arrested, the parts saved from injury, and thisparticular imperfectly-placed article allowed to proceed imperfectlywrapped and without injury to or stoppage of the machine. It will beunderstood that the folder A may be integral with arm (1, though thetwo-part construction with spring-joint shown is preferable. here thesemembers are integral, the relative location and shape of the partsshould be slightly modified, as will be obvious, in order to insureproper address of the operative end of the folder relatively to thewrapper. The folder A remains in the position shown in Fig. 6 untilafter rotation of carrierwheel E is resumed and is retracted by reasonof its connections with the main shaft, hereinbefore described, at themoment when the operation of bending down the remainingradiallyprojeeting portion 0 commences, which said last-mentionedoperation is effected as follows: To a stationary part or bearing D,rigidly secured to the arms a a, fixedly supported upon the part E, ismovably and yieldingly secured a brake piece or finger M. M is connectedwith D in substantially the same manner and by substantially the samedevices as A is with a, as hercinbefore describedthat is to say, i) isprovided with a pin or shaft (Z, upon which is journaled M, and ahelical spring is disposed around said pin with one of its extremitiesengaging against 1) and the other against M in such a way as to normallyforce M forward relatively to D, said action of said spring beinglimited by the engagement of a stop (1", adjustably secured to l),abutting against a shoulder m on M. M is disposed, as shown,substantially radially relatively to carryingwheel E, and is preferablyshaped so as to press first against the extreme end of aradially-projecting part of the wrapper 0 as shown in Fig. (5, the freeend of M being deflected somewhat in the direction of rotation of E. Bythis construction of parts itwill be observed that it is impossible forthe free operative end of M to abut against, indent,or be forced againsteither the wrapper or any more rigid projection from the pocket, thestop m preventing M from moving out of its normal radial position towardthe direction from which the pocket is advancing, and that thereforewhile spring is tensioned to afford M sufficient resistance to fold theprojecting portion of the flexible wrapper as latter is carried by italso allows H to yield or swing away from the periphery requiredwhenever-a more rigid projection from the pocket---as, for instance, anabnormally shaped or placed caramelis presented, all without cloggingorotherwise injuring the machine and without impairing BIs capacity tofold the wrapper.

Novel means are provided for holding to place the article andparticularly the aforesaid second side fold of the wrapper andsimultaneously, necessarily follows, the a foresaid underlying firstside fold during the continued rotation of carrier-wheel E and until thearticle is ejected from the pocket 0. Said means consist of a brush N,fixedly secured to said bearing D and preferably disposed so that itsfingers or bristles n extend from I) radially relatively to wheel 1C,and the tips of said bristles contact at all times with sufficientpressure against the outside surface of said second side fold of thewrapper. Said brush is preferably of the same width as the months oropenings of the pockets in carrierwhecl E and extends circumferentiallyand concentrically of the latter continuously from behind brake-piece Mto at or near the point where the article and its wrapper are ejectedfrom the pocket. There is thus provided an instrumentality whichcontinuously and with yielding pressure holds down to place as re- 1quired said second side fold and all parts 1 l l l 1 l l l thereof,notwithstanding variations in the location of said fold relatively tothe periphery of the wheel E due to inequalities in the shape of thearticle or irregularities in its presentation to and location in thepocket. It will be noted that, as shown in the drawings and as ismanifestly requisite to secure the action described,the said brush isconcentrically disposed relatively to the periphery of said wheel E; butit is manifest that the back or frame of the brush might be otherwisedisposed, so long as the field of the tips of the bristles thereof keptconcentric with the wheel.

Though unnecessary to a complete understanding of my present inventionas above described, .1 will add that the remaining folds in the wrappermay be made in any convenient way. For instance, an arm T is so pivo ted and actuated as to cause tucker-blades t" t", secured to the endthereof, as shown, to

IIO

swing inwardly and engage simultaneously on each side of the article thelaterally-projecting portions of the said side folds previously folded,as aforesaid, whichlast-described operation is effected while carrierwheel E pauses in appropriate relation to said tuckerblades, the saidside folds o of being in the position shown in Fig. 8 at the moment whenthe tucker-blades begin the operation of their function, as showncompleted in Fig. 9, and by which means the so-called first end tucksare imparted to the wrapper simultaneously on both ends of the article,after which the said arm T is retracted by swinging it outwardly tonormal position, and the rotation of carrier-wheel E is resumed. Afterthe said first end tucks are completed, as aforesaid, the carrier-wheelE resumes its rotation and the tucker-blades T T T T complete the endfolds. Said tucker-blades are yieldingly secured on shafts s .9, (seeFig. 4,) journaled in said carrier-wheel on each side of each pocket, asshown. Said shafts are each provided with a crank-arm 8, having awrist-pin .5 which engages in a suitably-located camgrooveas, forinstance, 8 s in fixed cam-disk E, the conformation of said groovesbeingsuch as to cause the blades T T to first swing forwardsimultaneously on opposite sides of wheel E into the positionillustrated by T Fig. 1, whereby the transversely-projecting portions 41o and in part '2) of the wrapper are on both sides of the articlesimultaneously folded forward and down to place upon the opposite endsof the article, after which T T are retracted to normal position by thecontinued action of the cam upon their said wrist-pins as rotation of Econtinues, and the blades T T are similarly actuated to swing backwardagainst the remaining transversely-projecting portions o o and in partn, whereby said last-mentioned portions are likewise simulta neouslyfolded down to place on both sides of the article, and the wrapper isbrought to the position shown in Fig. 10.

When the above described folds of the wrapper have been completed, thewrapped article is ejected from the pocket by any convenient means as,for instance, bya plunger 0actuated by appropriate mechanism, at theproper moment after the continued rotation of the wheel E has carriedsaid article beyond contact with the brush N, and thereafter theprojecting ends of the folded wrapper are bent down to final place uponthe article in any preferred way, Fig. 11 showing the appearance of theenveloped article after the wrapping operations are all' completed, thearticle in Fig. 11 being shown inverted as compared with itspresentation in Fig. 10.

I am aware that a wiper loosely suspended by links from astationarysupport and pressing by gravity against the periphery of the carrier tofold a flap of the wrapper has been employed; but such devices, as I aminformed,

have consisted of a plate of metal or similar heavy material ofsufficient weight to render the wiper operative by gravity alone and theportions of the wiper contacting with the wrapper have consisted ofrib-shaped members transversely disposed, so as to yield only directlyin a direction in which the wheel may be rotated, and I do not,therefore, wish to be understood as claiming any such construction.

It will be observed that while other means may he provided for holdingwithin the pocket of the wheel normally shaped and sized articles sucharticles as are accidentally too small or otherwise misshapen to be heldby such holding devices are nevertheless kept to place by the saidbrush, which may thus operate not only to retain in required positionfolds of the wrapper, but also during rotation of said wheel the entirearticle in process of wrapping.

I am also aware that brushes of limited contacting capacity have beenused as wipers to exert momentary pressure upon a pasted flap for thepurpose of increasing uniformity of distribution in the paste and alsoof causing the latter to adhere more immediately and tightly, andtherefore do not claim such use of brushes; but 1 am not aware that abrush of extended contacting capacity has been heretofore employed as byme without the assistance of adhesive material or other devices solelyto hold to place continuously an article and its unpasted wrapper,includinga fold of the latter, during extended carriage of such articleand Wrapper and While successive operations for imparting to the latteradditional and finally retentive folds are taking place.
